I tried to find something about the "Online Profile Links" by using the search function of this forum and I
found this entry (with screenshot) in a thread where earlier beta versions were discussed:

http://www.invelos.com/Forums.aspx?task=viewtopic&topicID=603174&PageNum=2&messageID=1753966#M1753966


It is possible to click on "Visit Profile Links Page..." and access the links from there but I thought these links should appear in the menu. Why is this "Copy Online Links" always grey and what is this function supposed to do if it were available?

Hmm, no more replies.
Invelos doesn't seem to care about such problems.
At least someone could give us the information if this is a bug or not.

Edit - just after posting this it stopped working on those titles, until I restarted profiler. 

It's working fine for me on those profiles that do have links, a couple of working examples:

5037899047248 - Castle Freak - UK
5039036060974 - A Good Day to Die Hard - UK

What I have noticed is it remains grey if the only link is Youtube.

Question is what's different on your systems compared to mine that's breaking the functionality. For what it's worth I'm using the default invelos skin in Profiler, so if you're not using that might be worth temporarily switching to see if it fixes it.
